Highly efficient and highly conductive phosphor-in-glass (PIG) material with additives for use as a white conversion component in laser-diode-driven white-light systems is introduced.
light extraction efficiency was investigated by modulating the ratio of the additive in a simulation using a light extraction model.
On the basis of simulation results for the proposed PIG, both transmission-type and reflection-type sapphire phosphor-in-glass samples were fabricated and evaluated
It has been confirmed that the sapphire powder significantly enhanced the light extraction efficiency and heat dissipation of the system.
